START/STOP LOGGING BUTTON
MASTER MESSAGE GROUP BOX
This button – located in the top, right corner of the interface – starts, pauses, or stops
the capturing of messages to the log file.
Before starting the logging process, select and open a log file (see Section 3.5.2 “Log
File”).
To pause the logging process, click the button a second time.
This functions in the group box to act as a master node on the LIN bus, sending the
previously constructed frames to the slaves on the bus.
This window will cause a bus conflict if another master appears on the network. Any
conflict will be shown in an active Transaction window as a bus error.
The group box, shown in Figure 3-7, consists of the:
• “Master Frames” field
• “Checksum” group
• Message controls
MASTER MESSAGE GROUP BOX
3.8.1
The “Master Frames” field is composed of 0 to n rows of one or more messages that
can be sent over the bus for test purposes. These messages can be entered manually,
loaded from a previously saved session, or both.
When the message is sent, it and any response is displayed in the Transaction window
if it is open and active.
Messages in the “Master Frames” field can also be saved for reuse (see
Section 3.4.2 “Save” and Section 3.4.3 “Save As”).
3.8.1.1
Messages must consist of the ID byte without parity bits and the data bytes, all
separated by spaces. All inputs are in hexadecimal radix.
The checksum is not included; it is calculated at send time.
Comments or notes may be attached to each frame by prefacing it with a
semi-colon (;). Any text after the semi-colon will be disregarded and not transmitted. All
notes will be saved in the selected .ini file and reloaded when reopened.
